Protein Target Calculator for GLP-1 Maintenance

Estimate a daily protein target based on ideal body weight. The goal is not bodybuilding. The goal is to preserve muscle, look healthier, feel stronger and make weight maintenance easier.

Why protein matters after GLP-1 weight loss

Ozempic, Wegovy and Mounjaro can make eating smaller portions easier. That also means protein can accidentally become too low. Low protein plus low resistance training is a weak maintenance setup.

Protein works best when paired with resistance training. Being generally active is good for health, but muscle needs a direct signal: lifting, machines, bodyweight exercises or bands. That matters for appearance, strength, metabolic health and longevity.

Calculate your planning target

Use either your height to estimate ideal body weight, or enter a clinician-agreed ideal body weight directly. The default target is 1.6 g protein per kg ideal body weight per day.

The formula estimate is only a planning tool. It is not appropriate for every body type, older frail patients, kidney disease, pregnancy, eating disorders or complex medical situations.

Lower-calorie protein sources

When coming off GLP-1 treatment, the trick is not just eating more protein. It is getting protein without accidentally adding too many calories.

Lean animal proteins

  • Chicken or turkey breast
  • White fish, tuna, shrimp
  • Egg whites plus whole eggs
  • Lean cottage cheese or skyr
  • Low-fat Greek yogurt

Plant-forward options

  • Tofu or tempeh
  • Edamame
  • Lentils and beans, portion-aware
  • Pea or soy protein powder
  • High-protein plant yogurts, check sugar

Easy structure

  • Protein first at each meal
  • 20 to 40 g per meal as a practical anchor
  • Add vegetables before calorie-dense extras
  • Use oils, nuts and cheese carefully

Training pairing

  • Two to four resistance sessions weekly
  • Progress slowly, but track progress
  • Prioritize legs, back, chest and core
  • Walking supports health, but it is not enough alone
